Examples of the implementation of non-destructive testing of structural transitions in polymer materials are presented. The method for determining the temperature of structural transitions is developed on the basis of the formulated boundary value problem of non-stationary thermal conductivity and its solution. When the polymers are heated, the values of the thermophysical properties change abnormally in the region of the structural transition. The measuring and thermal schemes of the method, the block diagram and the description of the measuring system are presented. The results of the experimental implementation of the method are presented.
